In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The first embodiment is as follows:
as shown in fig. 1 and 3, the water purification system of the present embodiment includes a first filtering structure 10, a water purification branch 20, a wastewater branch 30, a first switch structure 40, and a control device 50. Wherein the water purification branch 20 and the waste water branch 30 are both connected to the first filter structure 10 and located downstream of the first filter structure 10. The first switch structure 40 is disposed on the pure water branch 20. The control device 50 is connected to the first switch structure 40, and the control device 50 controls the first switch structure 40 to delay the preset time to open the water purifying branch 20 after receiving the water intake information.
With the technical solution of this embodiment, after the control device 50 receives the water getting information, the control device controls the first switch structure 40 to be turned on after delaying the preset time. Therefore, in the process of pressurizing the first filtering structure 10, the water purifying branch 20 is closed by the first switch structure 40 and does not discharge water, after the first filtering structure 10 is pressurized, the water purifying branch 20 is opened by the first switch structure 40 and starts to discharge water, and at this time, the water purifying branch 20 can continuously discharge water, so that the situation of water drainage and water cutoff is avoided, and the situation that the user experiences poor use due to water cutoff when taking water is eliminated. Therefore, the technical scheme of the embodiment overcomes the defect of poor user experience of the water purifier in the prior art.
In addition, the first filter structure 10 is pressurized for the predetermined time. Therefore, after the control device 50 receives the water getting signal, the first switch structure 40 is not turned on for a preset time, and after the preset time elapses, the control device 50 turns on the first switch structure 40, and the first filter structure 10 is pressurized, so that the purified water flows out from the purified water branch 20 continuously, thereby eliminating the water break.
Preferably, the preset time is in the range of 1 to 5 seconds. Specifically, the preset time is only required to be longer than or equal to the time for pressurizing the first filtering structure 10, and a person skilled in the art can adjust the preset time according to different water purifier structures. Further, the predetermined time should not be too short, which may result in the first filter structure 10 not being pressurized after the predetermined time. The preset time is not suitable to be too long, and the too long time can cause too long waiting time and reduce the use experience. Therefore, the preset time is preferably selected to be in the range of 1 to 5 seconds in the present embodiment.
As shown in fig. 1 and 3, in the solution of the present embodiment, the first switch structure 40 is an electromagnetic valve, and the first switch structure 40 is electrically connected to the control device 50.

Further, the control device 50 is also configured to receive the water intake information. Of course, the control device may be a mechanical structure mechanically connected to the first switch structure 40.
As shown in fig. 1, in the present embodiment, the first filtering structure 10 is a reverse osmosis membrane filter element. Specifically, after the raw water enters the reverse osmosis membrane, the filtered purified water flows out from the purified water branch, and the filtered concentrated water flows out from the wastewater branch 30 and is discharged through the wastewater solenoid valve. Further, the first filter structure 10 requires pressurization to perform the above-described function of filtering raw water.
As shown in fig. 1, in the technical solution of the present embodiment, the water purifying system further includes a water getting structure 60, the water getting structure 60 is disposed at the end of the water purifying branch 20, and the water getting structure 60 sends out water getting information. Preferably, the water intake structure 60 is a faucet. The faucet may be provided with a position sensor or the like to send water intake information to the control device 50. When the tap is turned on, the control device 50 controls the first switch structure 40 to be turned on after a delay of 1 to 5 seconds, at which time the purified water can be continuously discharged from the tap.
As shown in fig. 1, in the technical solution of the present embodiment, the water purification system further includes a raw water branch 70, the raw water branch 70 is connected to the first filtering structure 10 and is located upstream of the first filtering structure 10, a second switch structure 80 and a booster pump 90 are sequentially disposed on the raw water branch 70 along a raw water flowing direction, and both the second switch structure 80 and the booster pump 90 are connected to the control device 50. Specifically, the raw water branch 70 is used to introduce raw water. The second switching structure 80 is used to close or open the raw water branch 70, and preferably, the second switching structure 80 is also a solenoid valve. The booster pump 90 is used to pressurize the first filtering structure described above.
As shown in fig. 1, in the present embodiment, a second filtering structure 100 is disposed on the raw water branch 70, and the second filtering structure 100 is located upstream of the second switch structure 80. Specifically, the second filter structure 100 is a front filter element.
As shown in fig. 1, in the technical solution of the present embodiment, a third filtering structure 110 is disposed on the water purifying branch 20, and the first switch structure 40 is located upstream of the third filtering structure 110. Specifically, the third filter structure 110 is a rear filter element, and the first switch structure 40 is located between the third filter structure 110 and the first filter structure 10.
The embodiment also provides a control method of the water purification system, the water purification system is the water purification system, and the control method comprises the following steps:
after receiving the water intake information, the control device 50 controls the first switch structure 40 to delay the preset time to open the water purifying branch 20.
Specifically, when the control device 50 receives the water intake information, the control device controls the first switch structure 40 to be turned on after delaying a preset time. Therefore, in the process of pressurizing the first filtering structure 10, the water purifying branch 20 is closed by the first switch structure 40 and does not discharge water, after the first filtering structure 10 is pressurized, the water purifying branch 20 is opened by the first switch structure 40 and starts to discharge water, and at this time, the water purifying branch 20 can continuously discharge water, so that the situation of water drainage and water cutoff is avoided, and the situation that the user experiences poor use due to water cutoff when taking water is eliminated.
Further, the control method further comprises:

Specifically, when the control device 50 receives the water intake information, the control device 50 causes the second switch structure 80 to be immediately turned on, and simultaneously, the booster pump 90 is immediately started, so that the booster pump 90 boosts the first filter structure 10. At this time, the control device 50 does not turn on the first switching structure 40 immediately, but turns on the first switching structure 40 after a delay of 1 to 5 seconds. Within the above-mentioned 1 to 5 seconds, the booster pump 90 completes the boosting of the first filtering structure 10, so that the purified water can continuously flow out from the purified water branch 20 after the first switch structure 40 is opened, thereby eliminating the flow interruption.
The embodiment also provides a water purifier, which comprises a water purification system, wherein the water purification system is the water purification system.
